I'm excited to see who people ship Focalors with in Genshin. For now I don't see anybody that could be shipped with her that really does it for me personally.
Except perhaps I'm not really excited. I'm mostly just scared. The archon's history of shipping is varied. Zhongli has one super popular ship everyone knows. Ei is obviously with Yae. I personally think Venti goes best with Xiao, but I don't know if he has one perfectly concrete ship. Nahida's a child and I'm glad I never see ships with her in them.
Hoyo has a tendency to create characters in pairs for automatic investment and/or shipping. Think Beidou & Ningguang or Kaveh & Alhaitham. There are platonic pairings in there too like Nahida & Wanderer.
Focalors does have Neuvillette as her most explicit partner right now. But that ship doesn't satiate my soul. He seems like a proper fellow that just wants to keep up the law. But Focalors? I want her to be a gremlin. I need her to be absolutely insane and evil.
As such I expect people to ship her with whoever is the most unhinged and in opposition to her in Fontaine. Oh wait that's Arlecchino. Huh
